Broken Temperature Blend Air Door(s), improper heater replacement-door jammed & stuck in heat position, bad Actuator or unplugged, no refrigerant put back into AC after repair of heater. These are probably the most likely-any one & possibly multiple combinations.

I had refrigerant added. And the blend air door cable was snapped and the door stuck in heat position. Thank you. AC working now .
